The screen doesn't work at the moment, it comes on sometimes. I'm guessing loose wire. But the problem is i don't know what mode my heaters are on without the screen. Is there a way to get round that or do i need to fix the screen?

Hi,

When the screen is blank, does the system work? If not, then we need to check the power and ground circuits. See pics 1 and 2 below.

If it is only the screen, chances are there is a solder joint that is cracked in the printed circuit board that is making contact on and off, or the connection to power and ground are weak or loose. If you look at pics 3, I attached a pic of what each pin does at the connector. Pic 4 shows the power and ground pins. Check them to confirm there is no corrosion or damage.

Here is a link you may find helpful when checking the wiring:

Let me know what you find or if you have other questions.

Take care,
Joe
